Xiaomi probe needs to be pressed all the time to make a call.

The device only supports speaking by pressing.

The device only supports press-to-talk, so the Xiaomi probe needs to press-to-talk continuously.

Probe is the repackaging form of sensor and the most basic unit of sensor. The sensor is packaged by reasonable electronic circuit and external packaging structure, so that it has some independent functions we need. Like sensors, they are usually divided into thermal probe, photosensitive probe, gas sensor, force sensor, magnetic sensor, humidity sensor, sound sensor, radiation sensor, color sensor, taste sensor and video sensor according to their basic sensing functions. There are resonance sensors, broadband sensors, waterproof sensors, high-temperature sensors, low-temperature sensors and other special function sensors. Probe plays an important role in eddy current sensor system. Improper installation of the probe, making the probe too close to the metal body or the conductor area too small, will affect the formation of eddy current. Therefore, in the actual maintenance work, the installation and maintenance of the unit protection instrument probe should be strengthened to ensure the effective monitoring of the unit operation.
